TYPE-WRITER ATTACHMENT.

Application filed October 29, 1908. Serial No. 460,094.

To an whom it may concern:

Be it known that I, FREDERICK E. RIEG- GER, a citizen of the UnitedStates, residing at Newark, in the county of Licking, State of Ohio haveinvented certain new and useful Improvements in Type-VVriterAttachments;

and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such .as will enable others skilled in theart to which it appertains to make and use the same.

The present invention relates to a typewriter attachment and moreparticularly to the class of foot-actuating means foroperating the shiftkey, tabular bar, and the spacing lever. v

The primary object of the invention is the provision of a typewriterattachment comprising foot-operated mechanism for depressing the shiftkey, and the tabular bar, and for actuating the spacing lever of atypewriter of the ordinary construction, thus avoidingthe necessity ofmanually operating these parts as is now done,- and leaving the hands ofthe typist free at all tlIIIGStO manipulate the-keys of the typewriter.

In the drawings accompanying and forming a part of thiss ecificationisillustrated one form of embor iment of the invention which toenablethose skilled in the art to practice said invention will be setforth at length in the following descri tion, while the novelty of theinvention wil be included in the claims succeeding said description.However, it is to be understood that minor changes, variations andmodifications may be made such as come properly within the scope of theclaims hereunto appended without departing from the spirit of theinvention.

In the drawings: Figure 1 is a front elevation of a typewriter stand,typewriter and the invention applied thereto. Fig. 2 is a side viewlooking toward one end thereof and partly in section. Fig. 3 is asimilar view with the typewriter stand in section, and the typewriterpartly broken away. Fig. 4 isa fragmentary vertical sectional view inside elevation of one pedal mechanism. Fig. 5'is a vertical sectionalview in side elevation of the tabular bar and its pedal o cratingmechanism connected therewith. Fig. 6 is a fragmentary verticalsectional view of the standard and means for locking the same. v I

Referring more particularly to the drawings, the numeral 8 designates ina general manner, a typewriter stand of the ordinary construction, and 9at ypewriter of conventional form havin the usual shifting carriage 10,platen or ,roller 11 mounted thereon, spacing and resetting lever 12,tabular bar 13, and shift key 14, which are common parts of the ordinarytypewriter structure. Journaled in the lower part of the typewriterstand 8 and extending transversely centrally between the legs thereof isa rocking shaft or axle 15 forming the axis for a treadle 16, the

same being held in a normal inclined position by a spring member 17, thelatter having its bearing against the under face of the treadle at itsinnermost end and against the upper face of a base board 18'disposedbelow the said axle 15 and connected to the legs of the stand.

Connected to the inner end of the treadle 16 is a cord 19, the latterdetachably connected centrally to a hinged lever 20, which is pivotallyconnected at its real-most end as at 21 to the rear walls 22 of thetypewriter stand 8, the forward free end of the said hinged lever havingfastened thereto one end of a cord 23 which passes up through an opening24 formed in the stand top in which opening is mounted an anti-frictionroller 25 against which works the said cord. The other 'end of this cordis connected to a winding drum 26 journaled upon an axle 27 fixed to anadjustable bracket arm or standard 2.8, the latter being mounted at oneend of the typewriter stand. Upon the shaft or axle 27 and integral withthe drum 26 is a drum 29 having fixed thereto one end of a cable or cord30 which is adapted to be reversely wound thereon with respect to thewinding of the said cord 23 and its oppositc'end carries a hook 31 todetachably connect the same to the spacing and resetting lever 12 of thetypewriter. The said standard is constructed of a pair of telescopingtubes 28 and 29 and the former tube has a spring latch 30 provided witha lug 30 adapted for engagement in openings 31 formed in the tube 29 sothat the said standard can be lengthened or shortened as the occasionmay demand.

From the foregoing,'it will be apparent that the carriage 10 can bereadily returned to its initial starting position, subsequent to ment ofthe treadle pulling upon the cord 23 so as to unwind the same from itsdrum and at the same time, to cause the cord 30 to be wound upon thedrum 29, the unwinding of the latter cord having the effect of resettingthe carriage, owing to the connection of said cord to the lever 12.During the initial movement of the lever 12 which is effected as abovedescribed, the roller or platen 11 will be turned the desired number ofspaces, as set bythe spacing regulator, owing to the fact that the drums26 and 29 are located at a point sufficiently high above said lever topermit the curved or handle end of the latter to be raised. Spacing maythus be effected by the depression of the treadle 16.

On the axle 15 is mounted a foot treadle32 having below its toe and heelportions, depressible resetting springs 33 to normally hold said treadlein an inclined position. Each resetting spring has one of its endsbearing against the under face-of the treadle, While its op osite endbears against the base board 1'8. eneath the heel portion of the treadle32 extends the forward end of a supplemental treadle 34 which carries atsaid end a friction wheel 34 and is pivoted at its rear end to the baseboard. The front end of this treadle is held normally in raisedposition, with the roller 34 in contact with the under face of thetreadle 32 by means of a spring 35.

Connected to the foot treadle 32 at its too portion is a cord'36, thesame also detachably connected centrall'y of a hinged lever 37 pivotedas at 38 to the rear wall 22 of the typewriter stand and which lever hasconnection at its forward end through the medium of a cord 39 with thetabular bar 13 of the typewriter. Connected to the supplemental treadle34 is a cord 40, the latter being also detachably connected to a hingedlever 41 which has its rear end pivoted to the rear wall 22 of the stand8 said lever having its forward end connected through the medium of acord 43 with the capital shift key lever 14 of the typewriter.

To operate the tabular bar 13, the toe portion of the treadle is deress'ed by the foot of the typistso as to pu 1 upon the cord 36 and thusswing the lunged lever 37 downwardly, the cable connection 39 betweensaid lever and the bar effecting the actuation of the latter during themovement of the lever. The actuation of the bar will in turn shift thecarriage in the manner'known as jumpspace, for the tabulation of billsor accounts. When the shift key is to be actuated, the heel portion ofthe treadle is depressed, so as to act upon the sup lemental treadle 34,the depression of the a st mentioned treadle exerting a downward pullupon the cord 40, and thus lowering. the lunged lever 41, therebypulling downwardly upon the cord 43 with which the shift key isconnected.

4 It is obvious that the parts of the attachment are detachable topermit the folding of the typewriter stand should it be of this type.

What is claimed is 1. The combination with a tabular bar and a shiftkey, of a treadle operatively connected with said bar; and a secondtreadle operatively connected with said key and arranged for actuationby the first treadlc.

2. The combination with a carriage-resetting lever, a tabular bar, and ashift key, of a treadle operatively connected with said lever a secondtreadle o 'eratively connected with said bar; and a t iird treadleoperatively connected with said key and arranged for actuation by thesecond treadle.

3. The combination with a shift key and a tabular bar, of a rock shaft;a treadle secured intermediate its ends to said shaft; a spring arrangedto bear against each end of t 1e treadle; a treadle pivoted at one endand having the other end arranged to extend beneath the first mentionedtreadle; means for normally holding the last mentioned end of the secondtreadle in contact with the under face of the first mentioned treadleadjacent one end of the latter; and connecting devices between the otherend of the first mentioned treadle and said bar, and between the secondtreadle and said key, whereby said bar will be operated when one end ofthe first mentioned treadle is depressed, and the second treadle will bedepressed to operate said key when the other end of the first mentionedtreadle is depressed.

In testimony whereof, I affix my signature, in presence of twowitnesses.
